Tasmania's Singular Tree** When we sorted through photographer Matthieu Paley's images from his Tasmania trip, this shot captured the wild, ethereal vibe of the island itself. The graphic composition and the light make it work. In deciding to center the tree in the frame, Paley breaks the common "rule of thirds" here, which would call for setting the tree off-center (for an example, look at the boat captain opposite this tree). Yet it's knowing the rules - and when to break them - that's the key to this image's power. Another important tip is to keep shooting even on a cloudy day because it can create a dramatic, moody photo. "The right light is here for this kind of image: overcast with a bit of diffused light toward the end of the day," Paley says. "A threatening sky is good, too. As a photographer you have to be able to shoot in all weather conditions. I might use a neutral-density filter to bring the light down more and shoot wide open to give a shallow depth of field, which also creates a bit of a vignette look. If you shoot RAW [the unconverted, highest-resoluton image format], you can adjust settings to your liking in the computer later. I like to bring saturation down, maybe underexpose the image a bit, like on this picture - et voila!"
